13. Midamble Start
Bit Position/Sync
Pattern Start
Position
If Midamble Start Bit Position is displayed, the number displayed represents the
expected position (within the Burst Type you have selected) of the first bit of the
burst’s midamble. Example: If you have selected Burst Type TSC0, the Midamble
Start Bit Position will be 61, and you will see this number displayed in this field and
in the Midamble field to the right.
If Sync Pattern Start Position is displayed, the number displayed represents the
expected position (within a User Defined burst) of the first bit in a user defined
pattern that the DSP Analyzer will try to synchronize to. The field labeled Burst
Type must be set to User Def for Sync Pattern Start Position to be displayed.
14. Single/Cont
(Meas Trig)
Single performs one GSM measurement (DSP Analyzer, Pulse On/Off, and Output
RF Spectrum) after Meas Arm is selected and a valid trigger event occurs.
Cont performs GSM measurements continuously. Each time a GSM measurement is
performed, the measurement screen will be updated with new information.
NOTE
Screens that display traces update more slowly than screens that display numbers.
NOTE
If no measurements are being made while in continuous (Cont), check Trig Qual (see
Screens:RF Generator/RF Analyzer). If it is set to RF Power, change it to Normal.
15. Status (Use Mem) This field will indicate whether any data is available for a Use Mem measurement,
and whether current data has had a measurement performed on it. (The Use Mem
function allows DSP measurements over one archived GSM burst.)
•
No Data: No data has been stored.
•
Old Data: Data is available for a measurement, but Digital Demod has been
disarmed and then armed again since the data was stored. This indicates that a
measurement was made on the data.
•
New Data: Data is available for a measurement and Digital Demod has not been
disarmed and then armed again since the data was stored.

16. Sync Mode
This field selects how the location of the demodulated data bits are determined
within the measured burst.
Choices
Midamble attempts to bit pattern match the demodulated data bits
to the selected Midamble or User Defined Sync Pattern.
Amplitude centers the demodulated data within the detected
amplitude envelope.
